How can I understand the usage of "where appropriate" from the sentence "including where appropriate by recourse to arbitration"? I mean why plus "where" here?

The complete sentence is "commitment to settle by agreement, including where appropriate by recourse to arbitration, all questions concerning State succession and regional disputes."
